Effects of hydroaromatics on post-oxidation of polyolefins induced by electron irradiation
Additive effects of hydroaromatics towards radiation degradation and post-oxidation of high density polyethylene and isotactic polypropylene were investigated. At the same time, the radical scavenging effects of hydroaromatics were examined using DPPH(N,N-diphenyl-N'-picrylhydrazyl). It was found that:
1.
(1) the addition of HHAP (multi-component type hydroaromatics, produced by the hydrogenation of highly aromatic heavy fraction from petroleum) was obviously effective in inhibiting both radiation (electron beam in air) degradation and post-oxidation of polyolefins,
2.
(2) hydroaromatics (tetralin, octahydrophenanthrene and HHAP) have evident radical scavenging abilities from the tests using DPPH and
3.
(3) the inhibiting effects of HHAP can be attributed to its radical scavenging ability.
